.net實現導出Word、Excel格式文件

來自於：http://csharp.banzhu.net/article/csharp-2-74809.html

在做.NET項目時,會經常遇到要導出文件的問題,如將DataGrid中的數據導出到excel、word文件等,經常使用的是Office中的OWC組件,這個組件提供的功能很強大,在一般的項目中都可以滿足當前的需要.但是這個功能強大的組件使用起來卻不是很方便,不但有版本的問題,而且代碼量也相對比較大.現在簡單介紹一下利用Respone對象和相關的IO實現導出excel/word等文件的方法。

    1.Respone對象及相關的IO介紹
    System.IO.StringWriter SW = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter HTW=new System.Web.UI.HtmlTextWriter(SW);
    Page.RenderControl(HTW);
    //Page爲要導出的對象,當前是Page,如果是DataGrid,DataList等都可以
    Response.Buffer=true;
    Response.Clear();
    Response.ClearContent();
    Response.ClearHeaders();
    Response.ContentType = "Response.ContentType";
    //Response.ContentType是輸出流的 HTTP MIME 類型
    //Response.ContentType      --- word文件
    //application/vnd.ms-excel --- excel文件
    Response.Charset="utf-8";
    Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");
    Response.AddHeader("Content-Disposition", "attachment;filename=XXX.doc");
    //attachment --- 作爲附件下載
    //inline --- 在線打開
    //filename如過是中文,則可以用HttpUtility.UrlEncode(fileName,System.Text.Encoding.UTF8)進行編碼,以解決文件名亂碼的問題
    Response.Write(SW.ToString());
    Response.Flush();
    Response.Close();

    2.實現方法
    列出.net實現導出Word、Exce格式文件調用的具體方法，代碼如下：

/// <summary>

/// 將Web控件導出

/// </summary>

/// <param name="source">控件實例</param>

/// <param name="type">類型:Excel或Word</param>

public void ExpertControl(System.Web.UI.Control source, DocumentType type)

{

//設置Http的頭信息,編碼格式

if (type == DocumentType.Excel)

{

//Excel

Response.AppendHeader("Content-Disposition","attachment;filename=result.xls");

Response.ContentType = "application/ms-excel";

}

else if (type == DocumentType.Word)

{

//Word

Response.AppendHeader("Content-Disposition","attachment;filename=result.doc");

Response.ContentType = "application/ms-word";

}

Response.Charset = "UTF-8";

Response.ContentEncoding = System.Text.Encoding.UTF8;

//關閉控件的視圖狀態

source.Page.EnableViewState =false;

//初始化HtmlWriter

System.IO.StringWriter writer = new System.IO.StringWriter() ;

System.Web.UI.HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter(writer);

source.RenderControl(htmlWriter);

//輸出

Response.Write(writer.ToString());

Response.End();

}

//文檔類型

public enum DocumentType

{

Word,

Excel

}

    調用方法：
    ExpertControl(this, DocumentType.Word);
    這是將整個頁面導出爲Word
    //this可以爲具體的控件如datagrid/dataList或page表示當前頁，DocumentType爲導出的文件格式(Excel/word)
    注意：當爲datagrid或dataList控件時，在導出Excel/word文件時，必須把控件的分頁、排序屬性去除並重新綁定，否則將出現
"類型“DataGridLinkButton”的控件“DataGrid1__ctl14__ctl1”必須放在具有 runat=server 的窗體標記內。"錯誤!

    3.具體實例
    爲了讓大傢俱體理解.net實現導出Word、Exce格式文件功能，下面貼出一個具體實例代碼以供參考！　
    前臺代碼

<%@ Page language="c#" Codebehind="InSum.aspx.cs" AutoEventWireup="false" Inherits="FLX.Portal.InSum" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

<HTML>

<HEAD>

<title>InSum</title>

</HEAD>

<body>

<asp:Label id="Label1" runat="server" Font-Size="14px" Font-Bold="True">輸出形式：</asp:Label>

<asp:DropDownList id="DDLOutPut" runat="server">

<asp:ListItem Value="Excel">Excel</asp:ListItem>

<asp:ListItem Value="Word">Word</asp:ListItem>

</asp:DropDownList>

<asp:Button id="BtnOutPut" runat="server" Text="導出文件"></asp:Button>

<asp:datagrid id="DataGrid1" runat="server" AutoGenerateColumns="False" Width="100%" BorderColor="#CCCCCC"

BorderStyle="None" BorderWidth="1px" BackColor="White" CellPadding="3" AllowPaging="True"

Font-Size="12px" ShowFooter="True">

<asp:BoundColumn DataField="id" HeaderText="id"></asp:BoundColumn>

<asp:BoundColumn DataField="count1" HeaderText="count1"></asp:BoundColumn>

<asp:BoundColumn DataField="count2" HeaderText="count2"></asp:BoundColumn>

<asp:TemplateColumn HeaderText="count3">

<asp:Label id=lblQuantity runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.count3") %>'>

</asp:Label>

</ItemTemplate>

</asp:TemplateColumn>

</Columns>

</asp:datagrid>

</form>

</body>

</HTML>
